Review on 🌬️ Titan TTC-SC09TZ(B): Double Refrigerator Side Vent Fan + Speed Controller for RV, Motorhome, Caravan - 12V/24V DC, 120mm Multi-Function Rack Mount by Richard Mangum

Pros: The fan is very quiet and consumes little electricity. Cons: When the controller is set to manual, the fan runs at full speed and everything is fine. The thermostat does not work properly in automatic mode. The fan never turns off - I tested it from 90 to 36 degrees. At all temperatures, the fan just runs slower when set to Auto. At 90 degrees it runs even slower and needs maximum cooling. At 36 degrees it runs at the same speed, although no cooling is required and it has to switch off. The Min/Max slider does nothing at all. I reported the issue and to their credit they sent a replacement controller. Unfortunately, just like the original, it doesn't work. I replaced it with a simple on/off switch and the fan works fine with no temperature control. Also, there is no way to install an on/off controller. I need to find a way to mount it.
